The best description of how to find the equation of the line is: D. BD/DA = CE/CA, so 4/2 = y - 3/x ; solve for y to get y = 2x + 3.
<h3>How to Find the Equation of a Line?</h3>To find the equation of a line, find the slope of the line, using the equation: Slope (m) = change in y/change in x = vertical distance/horizontal distance along a line.
The slope of any two points on a line will be the same with any other two points on the same line. Therefore, the slope of the line in the given diagram is calculated as:
Slope (m) = BD/DA = CE/CA
Substitute
4/2 = y - 3/x
2(y - 3) = 4x
y - 3 = 4x/2
y - 3 = 2x
y = 2x + 3
Therefore, the best description of how to find the equation of the line is: D. BD/DA = CE/CA, so 4/2 = y - 3/x ; solve for y to get y = 2x + 3.

Answer:
a. A = -1 and B = 1
b. A = 7 and B = -5
Step-by-step explanation:
a.
To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:
Ax + Bx = 0
(A + B)x = 0
A + B = 0
A = -B
B - A = 2
B - (-B) = 2
2B = 2
B = 1 and A = -1
b.
To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:
Ax + Bx = 2x
(A + B)x = 2x
A + B = 2
A = 2 - B
2A + 3B = -1
2*(2-B) + 3B = -1
4 - 2B + 3B = -1
B = -5 and A = 2 - (-5) = 7
